- A convex lens is thicker at the centre and thinner at the edges. A concave lens is thicker at the edges and thinner at the centre.
Feb 20, 2022 · The concave lens is a diverging lens, because it causes the light rays to bend away (diverge) from its axis. In this case, the lens has been shaped so that all light rays entering it parallel to its axis appear to originate from the same point, \(F\), defined to be the focal point of a diverging lens.
6 days ago · Concave Lens is a diverging lens that scatters the incident light after refraction. Concave Lens is thinner in the middle and thicker at the edges. The images formed by a concave lens are virtual and erect. Learn more about concave lens, its types, applications, image formation and more in this article.

Lenses are often made of a thin piece of glass or plastic. Binoculars, telescopes, vision-correcting spectacles, torches, and microscopes are just a few examples.
Depending on whether light rays are converging or diverging, there are two types of lenses. There are two types of lenses: 1. The convex lens (converging lens) 2. The concave lens (diverging lens)
Pole (p): It is the middle point of the spherical lens or mirror.Centre of curvature (C):It is the center of the sphere from which the mirror is formed.Principal axis: It is the lines passing through the pole and the center of curvature of the lens.Principal focus (F): It is the point at which a narrow beam of light converges or diverges.Learn about concave lenses, their properties, types and applications. Find out how they form images of objects at different distances and use the lens formula to calculate the position and nature of the image.
Learn how lenses form images using the law of refraction and ray tracking. Find out the focal length and power of converging and diverging lenses, such as convex and concave lenses.
